ACTIA Multimedia Digital Cab is a rugged android-based Central ECU that can be connected to one or more full digital displays, safety ECUs and telematics. This multi-communication “Control Tower” gives access to state of the art infotainment and entertainment like radio and video but also connectivity and machine control functions. It gives the tractor or combine driver the same comfort, easy of use and safety as if he/she was in a car. Thanks to this new software-driven architecture and the range of touchscreens, equipment manufacturers can propose countless flexibility and the HMI personalization strongly requested by the market. Further manufacturer advantages include simplification, cost reduction and space gains.
Enabling smaller implements to connect into the ISOBUS easily and quickly, the innovation allows the visualization and control of 11 inputs and outputs for digital and analog signals directly at the tractor Virtual Terminal (VT). The complete configuration can be done at the VT with no configuration PC needed. This is an advantage as up until now, due to costs, mainly only larger implements have been supported by ISOBUS functionalities. With no licenses or memberships needed, the innovation is an opportunity for manufacturers of smaller implements to offer ISOBUS compatibility. Older implements also benefit with the available retrofit version designed for the aftermarket.
A further development of the carbide hoe blade for rougher working conditions on seedbed combinations, the carbide cultivator blade promises a consistent working quality, longer tool lifetime thereby savings on wear part costs. In order to better withstand the higher working speed at both greater working depths and impacts, a reinforcement with an integrated carbide tip is welded onto the cultivator blade. The beaver tooth effect and the constant working width ensure consistent quality of work while the saw tooth design effectively controls even stubborn weed. Herbicide use, the number of operations and fuel consumption can also be reduced. The stronger carbide segments maintain the wear ratio between the carbide inserts and the steel share and, with 60-80 tines on a 6 meter seedbed combination, the system ensures reduced downtime for wear part changes.
To measure and maintain a determined distance between an off-highway vehicle including implement and any obstacle, radar and ultrasonic sensors can work together. For collision warning and avoidance, the system is useful e.g. for a sprayer boom or while harvesting grapes as it ensures that the harvester maintains the optimal distance to the vines. Thanks to the object localization, the system not only warns the driver, but also delivers exact distance and position of other objects e.g. in parallel driving mode. The radar sensors can determine the position and direction of up to 40 static or moving objects simultaneously. Suitable for harsh environments, the system complies with IP69K and with any E/E-architecture of mobile machinery. Also Bosch camera systems can be combined or used individually with the previously mentioned systems for environment display and sensor visualization.
The rubber notched trapezoidal closing wheel has been designed for no till and direct seeding. The self cleaning wheel reduces the amount of mud and stubble sticking to the seed unit, ensuring an efficient wheel rotation and seeding. The notched profile eliminates the need for a notched steel metal disc conventionally used with closing wheels in direct seeding. The new rubber notched wheel has an easy assembly system and can achieve different working angles. The new development ensures precision seeding while reducing costs.
Most seed tubes drop seeds evenly if the tubes remain almost vertical in operation. However, as you drive up or down slopes, seeds often hang in the corrugations of the seed tubes. Often these seeds fall out in clumps when the seed tube straightens back out or when enough vibration shakes the seeds loose, resulting in inconsistent seed placement down the rows. BUCO corrugated seed tubes are made from neoprenne and provide excellent flexibility. BUCO seed tubes have internal folds above each corrugation, so as the seed tube stretches out, the folds direct the seeds away from the corrugations and help eliminate any seeds being held in the seed tube.
The new compact gear pump has been designed to offer both lower noise and vibration compared to conventional technologies, resulting in longer life of other components both in the hydraulic line and pump itself, which reduces the need to replace either part. The overall result is cost saving, energy efficiency and environmental benefits. Reducing the noise by up to 10 dB(A), the high performance of the pump eliminates the need for any end of line noise reduction measures, providing cost and space claim savings. At the same time, the low noise and low vibration helps protect operator health by minimizing exposure to occupational noise and vibration, improving comfort. The robust gear pump fits electric and hybrid machines, an area where noise is more perceivable and also applications from lubrication, steering and heavy duty operations.
The digital displacement pump creates hydraulic fluid power with both high efficiency and controllability using solenoid valves to actively control each cylinder on a shaft turn by shaft turn basis, a new method. This offers a fast response rate and reduces losses by up to 90 percent compared to conventional pumps. A new feature this brings is that groups of cylinders can be brought out to the endplate and controlled independently, thus producing a multi-service pump within a compact package. Up to 3 separately controllable outputs from one pump body are possible with the current product.
The solution consists of high processing power hardware and a software library that provides the electronics and software applications required for the functions on autonomous mobile machines such as navigation, positioning, perception, obstacle avoidance and sensor integration. Ethernet and CAN connectivity allow the controller to manage complex tasks and command machine sub-systems, such as propel, steering and work function. The library provides key software algorithms for advanced sensor fusion and autonomous navigation, and is built into pre-programmed function blocks saving development time. The systems provides short-time-to-market when the OEM adopts autonomous features. Suitable for harsh environments of the off highway sector, the rugged design complies with IP67.
With a range of ready-to-order rotary and linear drives, this new system meets the demand for automated electric vehicles requiring flexible actuator solutions that fits easily into any design. For the electrification, the motor employs next to the DC-motor itself a directly build in drive. This not only allows the control the motor it also offers the capability to directly program the necessary logic for an electric vehicle on the motor including communication to systems like the navigation. That reduces the need for several components such as external controllers and leads to an energy-efficient solution, reliable that offers, fuel savings and less impact on the environment at the same time.
This new electronic system guides the tractor dealer or the operator to create and save an intended pairing between one tractor and one implement, an advantage when dealing with farm fleets consisting of multiple hydraulic implements to be connected with multiple tractors. The benefits are improved fuel efficiency, predictive maintenance information, and contribution to safety through minimization of operator error. The hydraulic quick release coupling functions as an “intelligent node” recognizing the intended pairing. Once created by an expert user, the saved hose connection is suitable for repeated use. A unique RFID tag on each hose identifies the implement while an ECU, which transfers the information to the tractor, automatically adjusts the level of hydraulic power. Because the system detects the proper insertion of the coupling, it can also alert the operator of any accidental coupling disconnection during machine operation.
Featuring a 11-piston cylinder block and the swash plate on hydrostatic support, the new axial piston pump for hydrostatic transmission offers high pump efficiency resulting in fuel reductions of up to 10 percent. The mechanical contact between swash plate and pump body is eliminated, reducing noise by 3dB. A longer lifespan has been demonstrated and the compact and rugged design results in high power density. The system features a displacement ranging from 22 to 32 cm3/n with a maximum pressure of 450 bar, and an innovative oil distribution means the pump can reach 98 percent overall efficiency. The TPV 2500 is applicable with diesel, hybrid and electric engine.
Combining functionality, design and safety into one product, this newly developed lighting system suitable for the off highway sector incorporates three energy efficient LED light functions in one module: daytime running light, position and direction indicator light, all employing the innovative EdgeLight technology that provides a clear signature and homogeneous appearance without visible LED spots.. With the choice of three and five modules for each side of the off highway vehicle, the modular system offers design freedom. Whether horizontal, vertical or diagonal, flexible alignment options give each headlamp a strong individual character. The daytime running light further contributes to safety by reducing the risk of accidents caused by low visibility.
Maintenance costs today are often caused by the late detection of defects as modern equipment is quieter, making it challenging for the operator to react using his senses. This system supports early detection by measuring a series of parameters of the machine during work: engine speed, vibrations, temperature, GPS location and working hours. The benefits are not only lifetime extension and predictive maintenance but also documentation and early detection of technical issues.Easy to install and battery-driven, the device both transmits the real time data via Bluetooth to the smart phone and stores it for analysis and as a history record, useful in case of warranty claims or as documentation that the work was carried out.

The Pro Valve from MC Elettronica is a new valve for sowing control, equipped with an extremely powerful linear actuator capable of shut-off within 400 milliseconds. Due to the photoelectric sensor integrated in the valve body, the seed flow within pneumatic seed drills can be continuously monitored in real time and optimized via a control system and servomotors. This means that counting sensors can be integrated instead of just a blockage monitor, which further increases the potential of this new valve. In this way, the control and management of the seed and fertilizer flow are increased and can be fully and automatically linked to GPS-coupled application maps – an important technological step for the next generation of pneumatic seed drills.

With this overrunning clutch, the power flow is blocked in one direction by using cams between the housing and the hub. This ensures that the drive power is transmitted in one direction when reversing or turning the implement, an advantage because stopping inertia masses cannot damage the drive train and the machine. The direction of rotation can be adapted to the application and can be used universally in larger power classes. This compact freewheel clutch meets the demands of modern agricultural machinery drivetrains for both higher torque and more power while also freeing up valuable design space. Equipped with special bearings to counter the unintentional effect of torsional forces, the clutch ensures not only high operational safety but also a long service life.
Recording operating hours, utilisation and maintenance requirements of the PTO shaft on farm machines, the system makes maintenance and repair instructions available on the smartphone. Easy to retrofit and with clear visual display of the data, the Bluetooth-based app monitors the condition of the fleet thus supporting farmers and contractors in maintaining machinery regardless of manufacturer, model and age. Traditionally the correct timing of maintenance for cardan shafts and its components including the right amount of lubricants is challenging as documentation on machine use is often not readily available. Through the data collected in real time, the system offers to reduce not only avoidable maintenance costs but also the time invested, promising a time saving of up to 10 percent.
